Figure 4. Overexpressed miR-506-3p inhibited the expression of PI3K pathway-related proteins and enhanced the expression of related autophagy proteins. (A) Protein bands of PIK3CA, p-PI3K, t-PI3K, p-mTOR, t-mTOR, Beclin, LC-3II and ATG5. (B) Relative protein expressions of PIK3CA, p-PI3K, t-PI3K, p-mTOR, t-mTOR, Beclin, LC-3II and ATG5. **P < 0.01, nsP > 0.05.
